# Curve Position Curve Position is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Reads where price sits on its long-run growth curve: a full-history logarithmic regression with deviation bands 2 standard errors wide, position measured 0-100% across the corridor. Below 33.33% is low on the curve and longs have location, above 66.67% shorts do, the middle is equilibrium. A direction gate served with a dashboard showing the fit's point count. Walk-forward, so history does not repaint. - Indicator in the LuxAlgo Library, by LuxAlgo, published May 11, 2026. - Access: free. - Concepts: [Curve Position](https://www.luxalgo.com/library/concept/curve-position/) (primary) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=q5l3x1am16y2pe29fz3tntew - Page: https://www.luxalgo.com/library/indicator/curve-position/ **Curve Position** turns the [curve position](https://www.luxalgo.com/library/concept/curve-position/) question (where does price sit in the bigger picture?) into a measured readout. It fits a logarithmic growth regression (log price against log elapsed time) over the chart's entire history, wraps it in deviation bands 2 standard errors wide, and reads position 0-100% across the corridor. The fit is walk-forward (each bar uses the regression as of that bar), so plotted history does not repaint. ## How to Trade the Curve Position? - **Low on curve** (below 33.33%): longs have location and can aim across the corridor, the wholesale side of the map. - **High on curve** (above 66.67%): shorts have location, but strong trends can pin the upper band, so gate any fade with a trend filter. - **Equilibrium**: neither side holds a location edge; the framework's answer here is patience. - **Corridor break**: readings beyond 0-100% mean a band itself gave way. Reassess the map as the fit re-anchors. The dashboard reports position, zone, bias gate and the fit's point count; long daily or weekly histories make the location worth inheriting on execution timeframes. ## Curve Position Settings - **Source** (default close): series fitted; only positive values enter the log fit. - **Band Width (Std. Errors)** (default 2.0): corridor half-width in log space, so the bands stay proportional to price. - **Warm-Up Bars** (default 100): fitted points required before the curve, bands and readout display. - **Low On Curve Below (%)** (default 33.33) and **High On Curve Above (%)** (default 66.67): the zone boundaries. - **Show Zone Boundaries** (default on): draws the two separating levels on the price panel. - **Show Dashboard** (default on), with location and size options. - Style inputs cover the side colors, corridor gradient fills and optional zone transition markers. ## Frequently Asked Questions ### How does this differ from Premium & Discount? [Premium & Discount](https://www.luxalgo.com/library/indicator/premium-and-discount/) reads location against a dealing range's midpoint, an anchor that jumps with each new range. This build anchors location to a full-history growth fit, so the corridor evolves slowly and the read concerns the instrument's long arc rather than the current swing. ### Why does nothing plot at first? A regression over its first handful of bars means little and can distort the chart scale. The warm-up gate withholds the display until enough fitted points exist; the dashboard counts progress. ### Is a high-on-curve reading a short signal? It is permission, not a trigger. The framework gates direction by location and still expects an execution signal to do the timing, and the caution runs deepest in strong uptrends, which can hug the corridor's ceiling for long stretches. ## Related indicators - [Supply Demand Profiles](https://www.luxalgo.com/library/indicator/supply-demand-profiles/) (Supply & Demand Zones): markdown at https://www.luxalgo.com/library/indicator/supply-demand-profiles.md - [Supply and Demand Visible Range](https://www.luxalgo.com/library/indicator/supply-and-demand-visible-range/) (Supply & Demand Zones): markdown at https://www.luxalgo.com/library/indicator/supply-and-demand-visible-range.md - [Supply and Demand Daily](https://www.luxalgo.com/library/indicator/supply-and-demand-daily/) (Supply & Demand Zones): markdown at https://www.luxalgo.com/library/indicator/supply-and-demand-daily.md - [Rally Base Drop Signals](https://www.luxalgo.com/library/indicator/rally-base-drop-signals/) (Supply & Demand Zones): markdown at https://www.luxalgo.com/library/indicator/rally-base-drop-signals.md - [Supply and Demand Anchored](https://www.luxalgo.com/library/indicator/supply-and-demand-anchored/) (Supply & Demand Zones): markdown at https://www.luxalgo.com/library/indicator/supply-and-demand-anchored.md - [Support & Resistance Zones Strength Classifier](https://www.luxalgo.com/library/indicator/support-resistance-zones-strength-classifier/) (Zone Scoring & Refinement): markdown at https://www.luxalgo.com/library/indicator/support-resistance-zones-strength-classifier.md - [Rally Base Drop SND Pivots](https://www.luxalgo.com/library/indicator/rally-base-drop-snd-pivots/) (Supply & Demand Zones): markdown at https://www.luxalgo.com/library/indicator/rally-base-drop-snd-pivots.md - [No-Wick Retest Levels](https://www.luxalgo.com/library/indicator/no-wick-retest-levels/) (Support/Resistance & Levels): markdown at https://www.luxalgo.com/library/indicator/no-wick-retest-levels.md --- Source: https://www.luxalgo.com/library/indicator/curve-position/ (LuxAlgo Library).
